KELLY A1 TTORNEYS I plates 9 individually adjustable. Indetail, and as more particularly shown in Figures 5, 6, 'l and 8, eachof these side arms is journaled at its lower endupon the horizontalscrew I8 which is threaded into the block Il. This block is formed withthe internally threaded vertical bore I8 laterally outwardly beyond thescrew I6 and this bar is engaged by the machine screw I9 having the head20 rotatably engaging the loweiliori'aontal fiange 2| formed upon theextension plate 9. The upper end of the machine screwis journaled in thebushing 22 which has the head 23 rotatablj7 mounted in the upperhorizontal flange 24 of the extension plate. 'I'he machine screw isvertically positioned by suitable means such asthe pin 25 which extendstransverselythrough the bushing and the upper end of the machine screw,or by welding the machine screw to the-bushing as'at 2E'. 'The head 20is .preferably provided with the slot 26 for engagement by a screwdriver whereby l the machine screw may be rotated to thereby raise orlower the block il and with it the pivot for the lower end of the sidearm. 21 is a sheet metal cover which may be readily slipped over theextension plate and the associated mechanism and secured in place bysuitable means, such as the screws 28, which may be threaded into thehorizontal flanges of the extensionv plate.

From the above description, it will be readily seen that I have provideda window in which one or more ventilators are swung in unison withanother ventilator and in which adjustment may be readily made for theone or more ventilators to enable full closing of the same. It will alsobe seen that each adjustable device is readily accessible by simplyremoving its cover and, furthermore, that it may be adjusted when theventilators are in closed position so that considerable labor andexpense may be avoided.

What I claim as my invention is:

l. A window, comprising a frame, a plurality of swinging ventilators,means connecting said-ventilatorswhereby the same swing inunison,fulcrum means for said ventilators pivotally connecting said ventilatorsand' frame, one of the pivotal connections between said fulcrum meansand said frame and one of Vsaid ventilators being adjustable to providefor fuliy closing said last mentioned ventilator upon fullA closing ofthe -other of said ventilators, and means for adjusting said lastmentioned pivotal connection when said last mentioned ventilator isclosed.

2. A window, comprising a frame, a.4 plurality of swinging ventilators,and means connecting said ventilators whereby the same swing in unison,of side arms pivotally connected to one of said ventilators and alsopivotally connected to said frame, one of the pivotal connections oieach side arm being adjustable when the ventilator connected thereto isin closed position whereby said ventilators may occupy iiully closedpositions.

3. A window, comprising a frame, a plurality of swinging ventilators.bar means connecting said ventilators whereby the .same swing in unison,and side arms pivotally connected to said ventilators and also pivotallyconnected to said frame, one of the pivotal connections being.adjustable when the associated ventilator is in closed posiytionwhereby said ventilators may occupy fully closed positions. l .Y a. a

4. A window, comprising a frame, a swinging ventilator, means forguiding one endlof* said ventilator upon said frame, and fulcrum meansfor said ventilator pivotally connecting said vntilator and frame, saidguiding means having a predetermined limit of travel in a direction toclose said ventilator and one of the pivotal connections beingadjustable when said ventilator is closed whereby said ventilator may befully closed.

5. A window, comprising a frame, a swinging ventilator having a portionmovably'connected to said frame, fulcrum bar means pivotally connectedat one nd to anothei` portion of said ventilator, an adjustable pivotfor the other end of said fulcrum bar means, and means upon said frameadjustablewhen said ventilator is in closed positio-n for varying theposition of said adjustable pivot relative to said frame.

6. A window, comprising a frame, a swinging ventilator having oneportion movably connected to said frame, fulcrum side arms pivotallyconnected to another portion of said ventilator, ro-

screws and pivotally connected to said fulcrum side arms.

7. A window, comprising a frame, aswinging ventilator, means for guidingone end of said ventilator upon said frame, side arms pivotallyconnected at one end to said ventilator; plates upon said frame, screwsjournaled in saidplates and held from longitudinal movement relativethereto and blocks threaded upon said screwsA and piv'- otally connectedto the opposite ends of said side arms.

8. A window, comprising a frame, a swinging ventilator, means forguiding one end of said ventilator upon said frame, fulcrum side armspivotally connected at one end to said ventilator, extension platesfixedly secured to said frame and extending inwardly therefrom, each of'said plates having spaced apart substantially parallel flanges, a screwextending substantially parallel to said frame and rotatably carried byAsaid anges of `each extension plate, a block threaded upon each screw,and a pivot .for the opposite end of each arm carried by each block.

9. A window, comprising a frame, a swinging ventilator, fulcrum meansfor said-ventilator pivotally connecting said ventilator and frame, saidfulcrum' means comprising a side arm extending between adjacent bars ofsaid frame and'ventilator when the latter is closed and having'an endportion extending transversely of and beyond said frame bar, and anadjustable support upon and beyond said frame bar for said end portion.

10. A'window comprising a frame having a jamb, a swinging ventilator,means for guiding one end of said ventilator upon said frame, Iulcrummeans for said ventilator comprising an arm pivotally connected at oneend to said ventilator, and an adjustable pivotal connection between theother end of said arm and said jamb, said adjustable pivotal connectionbeing oil'set relative to said jamb and being adjustable when saidventilator is in closed position.

11. A window comprising a frame having a jamb, a swinging ventilator,means for guiding one end of said ventilator upon said frame, said meanscomprising a member pivotally connected to said ventilator, fulcrummeans for said ventilator comprising an arm pivotally connected to saidventilator and jamb, one of said pivotal connections being adjustableand being oset relative to said jamb and accessible when said ventilatoris in closed position.
